Thomas Nagel Quote

Once we have taken the backward step to an abstract view of our whole system of beliefs, evidence, and justification, and seen that it works only, despite its pretensions, by taking the world largely for granted, we are not in a position to contrast all these appearances with an alternative reality. We cannot shed our ordinary responses, and if we could it would leave us with no means of conceiving a reality of any kind.
